java program with unknown loop

I am making a program for school and I seem to have created a loop somewhere and I can't find the source. The program is supposed to prompt the user once for the color of the body, door, windows, and trim, and then print all three houses the same color. If someone could point out what I'm doing wrong, that would be great.

public class House
{
    public House(double x, double y, double width, double height)
    {
    this.x = x;
    this.y = y;
    xUnit = width / 12;
    yUnit = height / 8.5;
    }

    public void draw(Graphics2D g2)
    {
        // plot the points
        Point2D.Double p1 = new Point2D.Double(x, y - 5.5 * yUnit);
        Point2D.Double p2 = new Point2D.Double(x + 6 * xUnit, y - 8.5 * 
yUnit);
        Point2D.Double p3 = new Point2D.Double(x + 12 * xUnit, y - 5.5 * 
yUnit);

        // draw lines from the points
        Line2D.Double leftRoof = new Line2D.Double(p1, p2);
        Line2D.Double rightRoof = new Line2D.Double(p2, p3);    

        // construct rectangles to build the house
